Source: R/Binary.R
and_byname.Rd

Operands should be logical, although numerical operands are accepted. Numerical operands are interpreted as FALSE when 0 and TRUE for any other number.

Usage

and_byname(..., .summarise = FALSE)

Arguments

...

Operands to the logical and function.

.summarise

Tells whether the operation should be accomplished across lists (FALSE) or down lists (TRUE).

Value

Logical and applied to the operands.

Examples

and_byname(TRUE)
#> [1] TRUE
and_byname(FALSE)
#> [1] FALSE
and_byname(list(TRUE, FALSE), list(TRUE, TRUE), list(TRUE, TRUE), list(TRUE, TRUE))
#> [[1]]
#> [1] TRUE
#> 
#> [[2]]
#> [1] FALSE
